No.133,;49 l tClaim. (Cl. 2-3) This invention relates generally toface-shields and masks and more particularly to an eye-protective deviceto be worn primarily by workmen or mechanics as a protective measureagainst injury engendered by flying particles or the like.

()biects and advantages of the invention will be set forth in parthereinafter and in part will be obvious herefrom, or may be learned bypractice of the invention, the same being realized and attained by meansof the instrumentalities and combinations pointed out in the appendedclaim.

The invention consists in the novel parts, constructions, arrangements,combinations and improvements herein shown and described. Theaccompanying drawings referred to herein and constituting a part hereof,illustrate one embodiment of the invention, and together with thedescription, serve to explain the principles of to invention.

The invention has for its primary object, the provision of aneye-protective device having a bubble-shaped eyeshield which is readilyremovable therefrom and disposable in nature.

Another object of the invention is to provide an eyeprotective devicewhich may be simultaneously and conveniently worn over a pair ofspectacles.

A further object of the present invention resides in the provision or"eye-protective device constructed to permit of its use without aiiectingthe vision of the wearer.

Another object is to provide an eye-protective device of the characteraforesaid wherein the adjustable headband member is retained in headsize accommodating adjustment by cooperating action thereof with respectto the eye-shield member.

A still further object is to provide a device of this nature which isextremely light, flexible, non-shatterable, comfortably fitting andconvenient to wear or to carry.

It will be understood that the foregoing general objectives and thefollowing detailed description as well are exemplary and explanatory butare not restrictive oi the invention.

Referring now in detail to the present preferred embodiment of theinvention illustrated by way of example in the accompanying drawings,FIGURES 1 and 2 show the eye-protective device, designated generally bynumeral 1, suitably adjusted to the head of the wearer, the bulbouscharacter of the face-shield 2 being readily apparent. It

will also be observed that eye-glasses or spectacles may besimultaneously worn freely of interference with said eyeprotectivedevice by virtue of the bubble-shaped faceshield configuration, thusobviating any inconvenience otherwise encountered by the machine-workeror outdoorsman because of goggles, shields and other protective deviceswhich are inadequate in this respect.

it will be further noted that the majority of goggles and shields whichare useful in protecting the user against dust, wind, flying particlesand the like are worn close to the face and often cloud-up due to warmmoist air from the eyes being trapped and condensed on the insidesurface of the gogg'es. that clouding and fogging occasioned by poorventilation, abrupt temperature variations, warm moist air emanatingfrom the eyes and nose and other contributory conditions will beappreciably reduce and virtually eliminated by dint of the bubble-shapedconstruction disclosed herein.

In addition to the bubble-shaped face-shield construction and theadvantages attendant thereto, the invention further derives from thereadily removable and hence disposable nature of said face-shield 2,this feature being shown in FIGURES 7, 8 and 9, the latter figureshowing the face-shield partially removed with respect to headband 4 theassembled relation therebetween being disclose in FIGURES 4 5 of thedrawings.

The bulbous character of said face-shield 2, as shown in said FIGURES 8and 9, consists of a substantially elongated concavity having ahemispherically dished cross-section, a fiat upper marginal edge 6 andcontinuous side and bottom U-shaped marginal edges 8 and ill,respectively, said upper marginal edge 6 having a plurality oi grouped,spaced, linearly arranged holes or perforations 12 and singular hole orperfora ion 14, said holes 12 and 14- being positioned at opposite endsof said edge 6 as seen in the drawings.

The novel adjustable nature of said headband 4 and the cooperativeinteraction thereof with said face-shield 2 will be observed in FIGURES4 and 5 wherein said headband is seen to comprise ends 16 and 18, saidends being adapted to mutually overlap thereby producing superposedheadband portions in the region or" the forehead, tbis condition beingillustrated in FIGURE 2 of the drawings. Locating pins 2i? and Z2,integral with said headband, project outwardly therefrom at regionssubstantially inwardly of each said end 16 and 18, said projectinglocating pins being arranged for registration with one of said holes 12and hole 14, respectively, of said face-shield 2. Elongated angularmember 24, comprised of side 26 integral with upper edge 2.7 andperpendicular to said headband 4 in the region of end 18 and side 2%paralle spaced with respect to said headband, provide means cooperablewith said locating pins and said holes for ret ining said face-shieldand said headband in adjusted contiguous relation. To that end it willbe appreciated that subsequent to extending said locating pin 22 throughsaid hole 14, said end 16, slidably superposed with respect to said end18, is moved thereover until adjustment of said headband to the head ofthe wearer is attained, whereupon locating pin 2A) is extended throughthe correspondingly aligned one of said holes 12.

Elongated support members 369, 32, mounted upon said upper edge 27 ofsaid headband, journally support l..- shaped clamping wires 34, 36, oneof the legs thereof being pivotally and slidably received within resective passages provided axially thereof. Functionally, it will beobserved that said clamping wires are accordingly adapted for engagementwith said U-haped marginal edges 8 of said face-shield 2 to thus urge,by virtue of spring 37, said face-shield against the temples and face ofthe wearer. In view of the slidable association between said clampingwire and said support members,

Accordin ly, it will be appreciated registry of said clamping wires andsaid marginal edges may be accomplished notwithstanding the movement ofsaid support members during the aforedescribed headband adjustmentoperation.

Consonant with the readily removable nature of the face'shield withrespect to the headband, the replacement of a smeared, marred or brokenface-shield with a new face-shield of congruous proportions may bequickly effectuated. Accordingly, the bubbleshaped face-shields ofelongated hemisphere cross-section, may be stacked one within anotherand drawn from one by one as the requirement arises. It will be apparentthat automatic or semi-automatic dispensing means may be employed tofacilitate the replacement of face-shields, such dispensing means beingprovided in the plant or workshop or nearby any activity whereat theeye-protective device is being used.

Although the preferred embodiment of the device has been described, itwill be understood that changes may be made in the form, constructionand arrangement of parts from that disclosed herein without in any waydeparting from the spirit of the invention or sacrificing any of theattendant advantages thereof, provided, however, that such changes fallwithin the scope of the claim appended hereto.

What is claimed is:

An eye-protective device comprising an adjustable headband having endsadapted to overlap in the region of the forehead, locating ins integralwith and projecting normally of said headband, one of said locating pinsbeing positioned inwardly of each respective end of said headband, anelongate right-angled retaining member, one side thereof beingperpendicular to said headband, the other side being in spaced parallelrelation therewith, a support member connected to each respective end ofsaid headband, a spring biased clamping-wire slidably connected to eachsaid support member, a bubble-shaped face-shield member removablyassociated with said headband, said face-shield member having a fiatupper marginal edge and continuous side and bottom U-shaped marginaledges, said upper marginal edge having a plurality of spaced linearlyarranged holes provided therein, said clamping- Wires being eachurgingly receivable within respective side U-shaped marginal edges, saidflat upper marginal edge being restrained by said other side of saidretaining member, said locating pins being in registry with said holescorresponding therewith upon adjustment of said headband with respect tothe head of the wearer.
